INVENTOR CV/A/QZZS K ZZZ- Vf/P/VQ/l/JASORZA/V BY ATTORNEYS CARD AND HOLDER FOR FINGERP'RINT IDENTIFICATION SYSTEM This invention relates to an identification card and holder for use for personal identification.

It is an object of the present invention to provide a card and holder which is designed for use in a system wherein individual and distinctive data from a person such as a fingerprint can be recorded on the card for use with an identification system.

It is a further object of the invention to provide a card and holder wherein a light sensitive area on the card is protected against exposure until such time as it is properly positioned for the intended exposure.

Another object of the invention is a means for mounting a light sensitive material in a card for permanent use as an identification card, which card can carry written identification as well as a coded identification.

Other objects and features of the invention relating to details of construction accompanying the specification and claims wherein the principles of operation of the invention together with the use and the best mode presently contemplated are set forth.

Drawings accompany the disclosure and the various views thereof may be briefly described as:

FIG. 2, a rear view of the combination card holder and mask.

FIG. 3, a layout of the enclosing envelope of the card holder.

FIG. 7, a sectional view on line 7-7 of FIG. 6.

FIG. 8, a sectional view on line 8-8 of FIG. 9.

FIG. 9, a sectional view of the assembly with the light mask in masking position.

Reference is first made to FIG. 48 where a card in the form of a relatively stiff sheet I6 is shown. This can be made out of plastic material which can ultimately carry additional identification in the form of impressed or embossed letters.

It is intended to use the identification card in what is termed a coherent optical fingerprint identification system which utilizes the properties of coherent light and matched filter optical processing to compare a pre-stored hologram of a fingerprint to a real time hologram of a fresh fingerprint. The matched filter is an intensity recording of the phase and amplitude information of the Fourier transform of the fingerprint impression. This filter must be recorded onto a light sensitive material which will produce a partially opaque and partially transmitting image. This image, which actually is a filter in the cor relation process, is then placed within an optical system so that the matching operation may be performed. The light sensitive recording material for the system can be photographic film.

The identification sheet has a hole I8 which is surrounded on one surface of the sheet by an annular recess 20 in which lies a transparency 22. A larger annular recess 24 concentric with the hole I! and the recess 20 is also provided. The transparency 22 in the initial instance, when assembled, is a round disc of light sensitive material such as unexposed film, and it is held in place in the sheet 16 by heat staking the annular ridge 26 which lies between the recess 20 and the recess 24. After the film chip is placed in the position with the annular ridge 26, a hot tool is lowered onto the ridge which causes the plastic ridge to flow onto the edge of the film chip locking it into position. The temperature, of course, must be properly regulated to allow for the plastic flow without damaging the unexposed film chip. This staking is shown in FIG. 4B; the film disc 22 is securely held in place over the hole 18. If desired, the transparency 22 can be treated with an emulsion subsequent to the mounting in the sheet.

The sheet also has two spaced openings 28 and 30 which serve as locators in an apparatus described in copending application, Ser. No. 87,424, filed Nov. 6, 1970, entitled "Film Pack Locator Assembly."

The position of the three holes, that is, the aperture for the film and the two openings 28 and 30, is selected to minimize the change of position of the film chip hole which might be caused by temperature variation. The center of the film chip hole 18 must be located within 0.0005 inch in order to insure accurate results in the correlation procedures.

Once the card 16 is formed with the sensitive film 22 in place, it is necessary to protect it until the film is properly exposed and developed. An envelope is used for this purpose together with a light mask. The envelope is shown in layout form in FIG. 3 consisting of sides 32 and 34 each provided with openings 36 and 38 and 40 and 42 which respectively register when the sides are folded together to overlie the openings 28 and 30 of the sheet 16. The envelope panel 32 is provided with an opening 44 which registers with a similar but smaller opening 46 on panel 34, these being in registry with the hole 18 when assembled over the sheet 16.

The envelope also has an end flap 48 and an end flap 50 with one side flap 52. When the envelope is assembled, the end flap 48 and the side flap 52 are folded over the panel 34 and held in place by suitable adhesive, the flaps being fashioned to leave the openings 38, 46 and 42 uncovered, FIG. 2. The flap 50 of the envelope is turned so that it is on the inside of the side panel 34. This is best shown in the sectional view of FIGS. 7 and 8; the bight 54 between the panel 32 and the flap 50 will serve as a stop in a manner which will be described below. The material from which the envelope is formed is preferably a light blocking material and it may have a dull black inner surface to enhance this characteristic.

lnterleafed with the card 16 in the envelope and the walls of the envelope is a U-shaped masking member shown in FIG. 4A in layout having a main panel 60 and a side panel 62 joined by a bight portion 64. When this member is assembled into the unit, the bight portion rides along the inside of one folded edge of the envelope and the panel 62 is interleafed between the panel 32 and the sheet 16 as shown in FIGS. 7 and 8. The panel 60 which has a handle or grip extension 66 is interleafed between the panel 34 and the sheet l6 and extends outwardly between the flap 50 and the inside of the panel 34. Thus, the mask may be shifted longitudinally of the assembly by manipulation of the extending portion 66. When the mask is moved from the closed or inner position of FIGS. 8 and 9 to the position shown in FIGS. 6 and 7, the top edge 68 of the panel 62 strikes the bight 54 and stops the outward motion of the mask.

The mask has two opposed openings 70 and 72 which will register with the hole I8 when the mask is in its outer position. The mask also has two registering holes 74 and 76 which will register with the hole 30 in the sheet 16 and the holes 36 and 38 in the envelope when the mask is in the position shown in FIG. 7. The notched portion 78 is positioned so that it will expose the holes 40 and 42 of the envelope and the hole 28 of the sheet 16 when in the outermost position.

The mask is also formed of an opaque material such as black paper. The assembly shown in FIG. 1, 2 and a is in the sealed or protected position so that the film disc 22 is properly protected from light exposure. When it is desired to expose the identification card, it can be inserted into a proper apparatus where locating pins will engage the holes 28 and 30 position the opening 18 properly for exposure. At this time, the grip end 66 can be pulled which will move the mask slide to the position shown in FIGS. 6 and 7 to expose the film. A recording can then be made on the film in the form, for example, of a hologram of a finger print of an individual as described in copending application, Ser. No. 774,674, filed Nov. 12, 1968, entitled Method and Apparatus for Personal Identification." After exposure, the mask can then be moved back into the covering position and the card assembly can be taken to a developing room where the film disc is properly developed and fixed after which it will carry permanent recorded data which can be used in identification apparatus.
